Wireless Testing Question: Download Wireless Testing PDF

I just came across this url and could not help myself to comment on this. Your question looks little vague. I mean, are you talking about network level protocols or application level protocols. Or is it related to OBEX protocol implementation in Mobile Apps. Actually the same TCP/IP concepts go in mobile apps also, but when it comes down to browsing apps/downloading apps, it is generally done via WAP gateway (Not WAP Server which generally people confuse with). WAP is a standard defined to serve as a common platform as we cannot directly hook on from normal TCP/IP network to a mobile network. But it is definitely possible to call, SMS, sending mail from any browser to a mobile device, and vice versa. So how does this happen? Also are you talking about what happens at the server end, after the gateway or before that. Also, which carier network are you referring to GSM/CDMA. If I have sensed right it is "OBEX" you are referring to.
